The reason why I wondered about the above is that it can be an indication of another breakage, namely, that we may have tests that require a working ssh-keygen but are by mistake not protected with GPGSSH prerequisite. The test_lazy_prereq block you touched may refrain from setting the prerequisite on your system (due to the faulty test here that you touched), but if we had such unprotected tests, we still will run ssh signing tests and they would fail, due to the lack of the prerequisite. And fixing the prereq block alone will hide that other breakage, at least on your system. Hence my question. Thanks.
